How do I go about installing a solar system in my home. We live in Liberia W. Africa. We have 6 months of Rainy Season and 6 months of Dry Season. At present there is not a reliable source of Gov't supply electricity. So the system will be off grid. I am thinking about panels 12-120 watts or 10-130 watts panels. This is my frst experience with solar so I need all thae help and advice I can get. Please help.....
